Hot Dip Galvanized Steel Coil for Oil Pipelines

Galvanized steel coil is a special type of steel coil used in a number of different applications within oil pipelines. Steel coil of any kind is flat stock that is thin enough to be rolled into a coil or wound into a continuous roll. It can also be rolled out flat and cut at any length or shape needed. Having the steel coil galvanized helps the user by allowing it to be applied in outdoor oil pipeline projects.

Shanghai Metal Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.

Applications of Hot Dip Galvanized Steel Coil:

Galvanized steel coil can be used outside for diverse applications especially for oil pipelines because of its natural ability to avoid rust. Galvanized pipelines has been coated with zinc and this coating protects the steel from corrosion. It is most commonly used for outdoor and underground constructions.

There are two typical galvanizing ways to obtain a zinc coating: hot dip galvanizing and electrogalvanizing. Hot dip galvanizing is the process that steel is immersed into molten zinc bath to get a zinc coating surface. This not only helps protect steel from rust and corrosion, but also gives the steel a shiny attractive appearance. Electrogalvanizing is the process that uses electrolysis to coat the steel with zinc, which is neither cost-effective nor environmentally friendly. It is hardly to find electrogalvanized steel in our lives nowadays.

What are advantages of Galvanized Steel?

Because of permanent and successive zinc/iron alloy layers, galvanized steel offers many benefits:

1) Corrosion resistance: the zinc coating surface protects the base steel not only by providing barrier to corrosion elements, but also by the sacrificial nature of the coating. Galvanized steel often remains in working order with little maintenance for 40 years or more.

2) Excellent surface appearance

3) Formability: it can be simply bend to parts with deep drawing requirements

4) Paintability: it can be painted with different colors

5) Weldability: it is accepted various welding practices

What are disadvantages of Galvanized Steel?

In spite of many benefits, galvanized steel is not always an ideal choice. Galvanized steel cannot be used underground without being properly covered, which can be inconvenient for many jobs.

Where do we use Galvanized Steel?

It is primarily used in the construction industry, such as roofing, wall cladding, and support beams. It is also used in the automotive industry, due to its enhanced paintability, weldability and corrosion resistance. Moreover, it is an essential material for white goods application, such as refrigerators, air-conditioners, washers, microwaves, vending machines and audio visual systems.
